One of its standout features is the local U.S. connection, which enhances speed and reduces latency by avoiding foreign routing through China or Europe, making it a secure choice for data usage in the U.S. However, it's important to note that this SIM card is data-only, meaning it does not support voice calls or text messaging, which may be a drawback for some users who need a more comprehensive communication solution. The plan activates on first use, which provides flexibility and convenience, and you can manage multiple SIMs, data usage, and refills online through a single login.

Additionally, the SIM is compatible with most major devices that have a SIM card holder, adding to its versatility. Customer support is backed by Wave Connect's 10+ years of professional IoT data experience, which should provide some assurance for troubleshooting and assistance.
